12.8.3.5 DSA Signature Verification
1. Define a DSA callback function as per DSA generic callback API prototype, see the
API manual. If synchronous operation is preferred, instead simply pass NULL to the
API for the callback parameter.
2. Allocate memory for the operation
3. Populate data for the appropriate operation data structure, see the API manual
• Fill in the Flat Buffers; pointer to data and length
4. Call the appropriate operation perform DSA API
5. Completion of the operation, see Section 12.8.1
12.8.3.6 RSA Key Generation Type 1 and Type 2
1. Define a RSA callback function as per the API prototype, see the API manual. If
synchronous operation is preferred, instead simply pass NULL to the API for the
callback parameter.
2. Allocate memory for the operation
3. Populate the RSA operation data structure, see the API manual
• Fill in the Flat Buffers; pointer to data and length
4. Call the operation perform RSA API
5. Completion of the operation, see Section 12.8.1
12.8.3.7 RSA Encryption and Signature Verification
1. Define a RSA callback function as per the API prototype, see the API manual. If
synchronous operation is preferred, instead simply pass NULL to the API for the
callback parameter.
2. Allocate memory for the operation
